JOHN EGKS, OF MILWAUKEE, WISCONSIN.

CAR-LOADER.

To all 'whom t may concern.'

Be it known that I, JOHN Eens, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Car-Loaders, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to car loaders for loading railway box cars with coal or the like through the usual doorway in the mid die of the car and has for its object to provide a conveyer mechanism which may be quickly and easily run through the doorway of the car and projected to one end of the car for carrying the coal from an ordinary chute at the doorway to the end of the car.

Another object of the invention is to pro vide such conveyer with means for automatically raising its discharge end as the pile of coal discharged therefrom increases and also to provide it With means for retractlng it from the end of the car as the pile of coal advances.

Another object of the invention is to provide the conveyer with a mounting which will enable it to swing as well as to change its angle of inclination and permit of the coal being discharged at any point 1n the car.

Another object of the invention is to provide the conveyer witlr-a detlector which will change the direction of movement of the incoming coal so as to discharge 1t onto the conveyer in the same direction as the movement ofthe conveyor to relieve the conveyer of Wear.

Another object of the invention 1s to provide the car loader with a pivotal mounting which will enable the entire machine to be turned to a position parallel with the car and will enable it to operate upon cars on tracks on either side thereof.

Another object of the invention is to perfect details of construction of car loaders.

With the above anditlier objects in view the invention consists in the car loader as herein claimed and all equivalents.

Referring to the accompanying drawings in which like characters of reference indicate thel same parts vin the different views: Figure 1 is a side view of a car loader con- Iat-ented Sept. 9, 1 91 3.

structed in accordance with this invention 1n position for delivering coal within a car; Fig. 2 is a plan view thereof; Fig. 3 is a sec* tional elevation of the car loader with the sliding frame retracted and the conveyor frame swung to a position over the slidlng frame, the position of the machine when not in use; Fig. L1 is a detail view on an enlarged scale of the pivotal and swinging mounting for the conveyer frame; Fig. 5 is a transverse sectional view `through the conveyer frame on thc line 5-5 of Fig. 3; Fig. G is a transverse sectional view through the base frame and the sliding frame on the plane of line 6--6 of Fig. 3; Fig. 7 is a detail sectional view showing the pivotal connection for the swinging frames; and, Figs. 8, 9, 10 and 11 are diagrams showing the method of entering the car loader through a car door ropening and of manipulating it therein for filling both ends of the car. n

1n these drawings 10 indicates a foundation or support which may be stationary or movable and on which is mounted a spider 11 carrying beveled rollers 12 arranged in a circle to constitute a pivotal bearing together with an upright king bolt 13 in the f rame at the center of the circle for a turntable 14 which has a beveled tread bearing on the rollers and a central hub fitting on the king bolt. A pair of channel iron beams 15 are securely mounted on the turn table 14 and are connected together at intervals by cross pieces 1G to form a rectangular frame 4 which, to distinguish from other frames in the mechanism, will be referred to as the base frame. A series of standards 17 are carried by the beams 15 of the base frame to form supports for rollers 18, each standard having a pair of such rollers, one higher than the other as seen in Figs. 1 and 3 and one nearer to the middle of the base frame than the other as seen in Fig. 2. These rollers 1S constitute the support for a sliding frame formed by a pair of I-beams 19 and their cross connections 20. The I-beams 19 bear upon the lower rollers 18 and have. the upper rollers 18 positioned in the space between thc upper and lower flanges thereof on the outer side of the frame and riding upon the lower flange to keep the sliding frame from tilting when in its extended position, as shown in Fig. 1. The movements of the sliding frame on its roller bearing v.tionto the sliding frame.

support are produced by a cable mechanism, shown in Fig. 3, a cable 2l being attached at one end to an end of the sliding frame and passing around a pulley 22 on a shaft 23 at the opposite end of the base frame, and then around a drum 24 on a shaft 25 extending across the intermediate portion of the base frame, and then around another pulley 22 on the shaft 23 at the other end of the base frame and then connected at its other end with the opposite end of the sliding frame. The drum 24 is turned by a sprocket cha-in connection 26 connecting its shaft 25 with a crank handle 27. By turning the crank handle 27 the sliding frame is easily moved in either direction. At one end of the sliding frame the I-beams 19 thereof are connected by heavy cross rods 2S which form the supports for a turntable base 29 which has a turntable 30 mounted on a king bolt 31 standing up from the center of the hase 29 and bearing on conical rollers 32 between the beveled bearing surfacesr of the base and turntable. At the portion of the sliding frame not occupied by the turntable there is a platform or decking 33 on which the operator may stand. A' pair of channel iron beams 34 are secured to the turntable 30 and together with their cross connections constitute av turning frame for swinging the conveyer mechanism fro-m side to side within the car and for turning the conveyer mechanism to any desired angularity with rela- These channel beams 34 have supporting brackets mounted on them, as best seen in Fig. 4, and rocking frames 36 are pivotally mounted on them by being suspended on stub shafts or studs 37 which project from the brackets 35. The rocking frames 36, as shown in Fig. 4, have rollers 38 at their upper corners which support a conveyer frame formed by a pair of channel iron beams 39 and their cross connections, the rollers 38 fitting in the recesses between the anges of the beams 39 and having the upper flanges bearing thereon. The cross connections for the conveyer frame are not directly between the beams 39 as said beams form the side guide walls for the conveyer, but cross pieces are in the form of angle iron strips 40 connecting the lower edges of the beams 39 at intervals. Also there are brackets 41 secured to the lower edges of the beams 39 and angle iron strips 42 are astened to the lower ends of the brackets and have a sheet metal decking 43 mounted on them and extending beneath the conveyer the full length and width thereof. At each end of the conveyer there is a roller 44 around which a conveyer belt 45 passes,

its upper length forming the conveying p ortion and bein supported against sagging by rollers 46 Journaled in the brackets 41 and by supporting strips 47 which are secured to the lower edges of the beams 39 with the edges of the conveyer belt hearing thereon.

The sliding movements of the convey-er frame en the pair of swinging frames 36 may be produced in the same manner as with the sliding frame 1f), a cable 4S having one end attached to one end of the convover frame and passing around a drum 49 on a shaft 50 journaled in the swinging frame Il() and then connected at its other end to the other end of the conveyer frame. 50 may be turned by means ot a crank handle 51, Fig. 1, for accomplishing thisl sliding adjustment of the conveyer frame and may be locked, as shown in Fig. 4, by a sliding bolt 52 onone of the swinging frames 36 engaging a notched disk 53 on said shaft 50. The lower length of the conveyer belt passes over a pair of pulleys 54 journalcd in the swinging frames 36 and around a driving pulley 55 also journaled in said swinging frames on a shaft 56 which carries a gear wheel 57 in mesh with a pinion 58 on a sleeve 59 loosely mounted on oneof the studs 37. This sleeve 59 is driven by a sprocket connection 60 from an electric* motor 61 or other driving means mountedV on the extended ends of beams 34, best seen in Figs. 1 and 2.

The tilting movements of the conveyer frame are produced by worms 62, Figs. 3 and 4, on shafts 63 which are journaled in The shaft the beams 34, said worms meshing with.v v

worm racks 64 on the lower ends of the swinging frames 36. The worm shafts 63 have worm Ojears 65 meshing with worms Y 66 on a shaft 67 journaled in brackets 68 on one of the beams 34 and said shaft 67 has a clutch 69 operated by a lever 70 for coupling it with a sprocket chain connection 71 of sleeve 59 so that the motor driven sleeve will impart motion to the shaft 67 when the clutch is closed to cause the turning of the worm shafts 63 and the swinging of the swinging frames 36 and the conveyer frame mounted on them.

The coal or other material to be loaded in the car is received bythe conveyer from any suitable spout 72, Fig. 1, or other delivering means which connects with a hopper or delector 73 mountedron the swinging frames.

frame through the doorway as shown by the diagrams in li`igs. 9. tl, ltl and ll. l `rom the position oll the partsl shown in Fig. it the eon\'e \'er t'ranie is swung until its outer eml enters the ear door opening` as shown iu liig. s. on its pivotal support and also turning the eon\'e \'er t'rame on its turntable the base trame is swung to a position at approximately a right angle to the ear while the eon\'e.\'er l'rame entersl through the ear door opening to the other side ol' the ear. as shown in l"ig. .l. 'l`hen the slidingI t'rame is moved upwardl)Y through the ear door opening until lthe turntable it() thereon is near the eeuter ol' ther ar and the eouveyer trame reaehes to the end ot' the ear. Now the maehine is ready for loading the ear and the eoal or other material led tio the hop per or delieetor T23 is directed by the hinged plate T-t to that ehute thereof whieh leads in the direetion of the travel of the conveyer belt so as to deliver the eoal onto the eonveyer belt by whieh it. is earred to the end oi. the ear. A\t the beginning ot the loading operation the eonveyer frame is tilted downwardly and as the pile of eoal at, the end of the ear inereases in size the eoinever trame may be ehanged in its angle ot inelination by thel manipulation of the eluteh lever 70, sueh eluteh lever being preferably thrown to close the eluteh so that the ehange in angnlarity ot' the eonvever `trame will be continuous and automatie until the pile of eoal is as high as desired, the eon\'e \fer frame having been gi".1duall shifted from a descending position to an aseending position. As the loading progresses thel eonveyer frame may be retraeted and when one end of the ear is loaded it is not neeessary to further ehange the angularit)v ot' the eonveyer frame. but the lateh 52 is released andl the shaft 5() is turned to slide 'the eonve'ver trame to the other end ol` the ea and the hinged plate T-t of the hopper or detleetor is swung to tlu` other lside and the motor is started in operation, but in the reverse direetion. The loading ol' the other end ot the. ear is aeeomplished in the same manner as above deserihed and when this is completed the ear loader is withdrawn from the ear by the reversal ot the operation by which it was entered. During the filling the eonve ver iframe may be swung on its turntable from side to side so as to reaeh every part oi. the ear.

ly means of this invention the loading of box ears with eoal and the like may be quickly and easily accomplished by reversing the position of the hopper or defleetor 73. The divided hopper or tlelleetor enables the eoal to be delivered to the eonveyer belt in the direetion in whieh the eonveyer belt. is run when filling either end of the ea and thus materially reduces the wear upon the 'l`hen b'v turning the base frame1 eon\'e \'er belt. 'l`he machine being capable ot oeeupying a position parallel with the ear enables the traelts to be placed close together. 'l`l1e metal deelting -t serves tio eateh sueh eoal as ma)Y tall from the e011- veyer belt and prevent its being taken along with the return portion ot" the eonveyer belt.
